Failed to install ocaml 4.07 and 4.08

[webhive]

When tried to install recent versions of ocaml got the following error

asdf install ocaml 4.08.1

  In normal operation, opam only alters files within ~/.opam.

  However, to best integrate with your system, some environment variables
  should be set. If you allow it to, this initialisation step will update
  your bash configuration by adding the following line to ~/.bash_profile:

    test -r /home/roman/.asdf/installs/ocaml/4.08.1/opam-init/init.sh && . /home/roman/.asdf/installs/ocaml/4.08.1/opam-init/init.sh > /dev/null 2> /dev/null || true

  Otherwise, every time you want to access your opam installation, you will
  need to run:

    eval $(opam env)

  You can always re-run this setup with 'opam init' later.

Do you want opam to modify ~/.bash_profile? [N/y/f]
(default is 'no', use 'f' to choose a different file) A hook can be added to opam's init scripts to ensure that the shell remains in sync with the opam environment when they are loaded.
Set that up? [y/N] y

while the version 4.06.1 installed well

[yeongsheng-tan]

On my macOS 10.14.6, I could not even get 4.06.1 to install correctly. 4.07.1 and 4.08.1 failed similarly as per below too:

@webhive Can you provide more detailed environmental information?

[smorimoto]

Both versions were installable in all my environments. (macOS 10.14.6, OpenBSD 6.5) Maybe you don't have the required dependencies and I'll check it out this weekend.

[smorimoto]

If you need a template for environmental information, use the following one.

- OS: [e.g. macOS 10.14.6]
- asdf version [e.g. v0.7.4]
- Is the asdf-ocaml up to date? [e.g. Yes or No]

To update asdf and asdf-ocaml, run the following command.

asdf update
asdf plugin-update ocaml

[yeongsheng-tan]

I'm on macOS 10.14.6.
I was on asdf v0.7.3.
I'd just upgraded to asdf v0.74 and updated my asdf-ocaml plugin (asdf plugin-update --all).

I re-ran asdf install ocaml 4.08.1 and am still getting the below:

What else could I check?

[yeongsheng-tan]

Seems like it does not work across available ocaml versions of 4.06.1, 4.07.1 and 4.08.1 for me at all.

Similar errors as above.

What else could I help provide to narrow down the potential issue?

[webhive]

$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.14.6
BuildVersion:   18G87

ASDF installed using brew

$ asdf --version 
v0.7.3

• Is the asdf-ocaml up to date? Yes - installed it again as previously was removed

So now I got it working well

Thank you!

[webhive]

@yeongsheng-tan

Similar errors as above.

These errors is not related to this plugin - try opam switch without asdf - I believe you will get same result. These errors related to installed libraries

[smorimoto]

Yes, this plugin recently supported macOS and OpenBSD. So I guess that the build failed because of some required dependencies are missing.

[smorimoto]

@yeongsheng-tan If you can send me a list of what you have installed with brew, I may be able to look into your issue a little more.

[smorimoto]

I will close this issue, but any comments are welcome.

[yeongsheng-tan]

@yeongsheng-tan

Similar errors as above.

You are right. I did brew install opam and tried opam install ocaml and opam switch and
I tried updating my asdf to version v0.7.4 and asdf-ocaml to the latest using asdf plugin-update --all. I then downloaded latest Xcode 10.3 Command Line Tools (macOS 10.14) and installed.

Not sure what other packages/lib are required. Any LDFLAGS I need to set for opam or gcc to compile the needed? My asdf install ocaml 4.08.1 is still failing as before.

[smorimoto]

My friend could install 4.08.1 in his environment without any additional ways. I prepared a completely new macOS environment, so let's try something in that environment.

[yeongsheng-tan]

Found the fix for macOS 10.14.6 in this github issue: ocaml/opam-repository#13008

Basically, the main idea/fix is to brew unlink binutils

From ocaml/opam#3650

Finally:

 yeongsheng@yeongsheng  ~  asdf install ocaml 4.08.1                                                                                                                                                                  ✔  10097  22:49:27

@yeongsheng-tan I’m glad to hear that 👏

[yeongsheng-tan]

@yeongsheng-tan I’m glad to hear that 👏

Everything fell nicely into place w/o any errors with opam install thereafter. macOS 10.14.6 w/o binutils from Homebrew that is.

asdf global ocaml 4.08.1
opam install -y async core js_of_ocaml js_of_ocaml-ppx merlin utop ocp-indent

works perfectly for me now.

[smorimoto]

Thanks for the information. This issue is likely to be help to others, so I pinned this!

[smorimoto]

I created new version that install OCaml without Opam. You should be able to install it without brew related problems. More context can be found in #15.
